To. all whom it may concern:

Be it known that I, STANLEY- A. MA TINEK, a citizen of the United States, residing at Amarillo, in the county of Potter and State of Texas, have invented certain new and useful Improvements in Priming-Cups for Internal-Combustion Motors, of which the following is a specification.

This invention relates to a priming cup for internal combustion engines or motors and an object of the invention is to provide a priming cup which is screwed into the head of the motor, which is simple in con-, struction, durable, and easily operated to permit the volatile fluid to flow therethrough into the cylinder to the engine,

More specifically, the invention comprehends the provision of a rimer or priming cup as specified, which inc 'udes. a casing having a shank thereon, which is threaded into the cylinder head and in which casing is mounted a longitudinally movable; spring controlled valve member having a head upon its upper end provided with an annulargroove adapted to engage over a portion of the casing to hold the valve in an open p0: sition and which head springs: or moves into the opening in the casing through which a head projects, to reseat the valve cone. and shut off the passage of fluid to; the priming cu (sther objects of the invention will appear in the following detailed description taken in connection with the accompanying drawing, forming a part of this specification and in which drawing:

Figure 1 is a side, elevation of the improved priming cup showing the same 'applied to a fragment of an internal combus-, tion engine.

Fig. 2 is a longitudinal section through the priming cup showing the valve closed, and

Fig. 3 is a longitudinal section through the priming cup showing the valve open.

Referring more particularly'to the drawing, A indicates a fragment of an ordinary internal combustion engine or motor, the head B of which is provided with a threaded; bore C. This threaded bore C receives therein the threaded end 1 of the shank 2 of the casing or main body 3pof the priming cup to connect the priming cup to the engine. The head B is provided with a polygonal face 4 to permit it to be gripped by a wrench for properly connecting it; to the cylinder head B, and it is, also provided with a I'Qlitr. tiv'ely large recess 5 therein which opens out through a constricted opening 6 in. the up; P d. f the bo y- I T S an 2 is. Pr vided with an axial; bore 7, the upper end of which is, enlarged as shown at: 8 to receive therein the lower end of the, spiral spring 9 and also to form a shoulder against which the'lower end of the said spring abuts. The Spring 9; is coiled about the valve stem 10 and its upper end abuts against the inner end of the head 11 which is detachably mounted upon the upper end of the. valve stem 10. This head 11 is provided with a substantially conical cup or recess 12 open, ing out at its upper end which communicates with a transverse bore 1 3 in the head through an axial bore 1a, The transverse bore 13 is formed in the. head 11 so that it will be at all times positioned within the recess 5.

The, head 11 is provided with an annular recess 15 which is, normally positioned out of the casing or body 3.

When it is desired to prime the. internal combustion engine with which the improved priming cup is used, the spouts of an ordinary oil can as indicated at D in Fig. 3 of the drawings is inserted into the recess 12 and the head 11 is forced inwardly against the tension of the spring 9 for unseating the valve cone 16 which is carried upon the lower end of the stem 10 and normally rests in the valve seat 17 formed in the lower end of the shank 2. After the head 11 and stem 10 has been forced inwardly to unseat the valve cone 16, they are forced laterally, a short distance so that the flange which S111", rounds the opening 6 will be engaged in the recess 15 and the expanding action of the spring 9 will force the lowenwall of the annularrecess 15 into firmengagement with the flange of the body 3 which surrounds the opening 6,, maintaining the head 11' and the valve stem 10 in their angular positions, allowing gasolene or other volatile fuel, which. may be forced into the recess 12 from the can D to flow through the ducts 14 and 13. into the recess 5 and through the axial bore 7 through the shank 2 into the'engine. Aslight lateral pressure on the head 7 to move it sufficiently to disengage the flange of the body 3 from the annular channel 15 will allow the spring 9 t seat the head in the opening 6 and also seat the valve cone 16 cut: ting off the flow of fluid thro gh he P imins c r- Changes in details may be made without departing from the spirit of this invention, but;

I claim:
